HPE M-Series 100GbE QSFP28 1310nm PSM4 500m Transceiver

Meet the HPE M-Series 100GbE QSFP28 1310nm PSM4 500m Transceiver, a purpose-built fiber interconnect that blends speed, reliability, and scalability for modern data centers. When organizations deploy dense compute resources—whether in cloud-scale, high-performance computing, or enterprise virtualization—the need for consistently strong uplinks between servers and top-of-rack or aggregation switches becomes a bottleneck. The HPE StoreFabric M-Series transceivers are engineered to address this challenge by delivering multi-gigabit throughput with low, predictable latency, while reducing the number of hops across your fabric and simplifying cable plant management. This transceiver uses a 1310 nm PSM4 interface in a QSFP28 form factor, enabling four parallel lanes of 25 Gbps each, for a total of 100 Gbps of aggregate bandwidth. The 500-meter reach on single-mode fiber OS2 makes it ideal for mid-size to large data centers, campus networks, and inter-building connections, where longer fiber runs and higher connection quality are essential for maintaining service levels under peak load. By aligning with the HPE StoreFabric M-Series, you gain interoperability with other StoreFabric components and a coherent performance envelope across your fabric—so you can tune workloads, balance traffic, and preserve low latency as you scale. In practice, this means you can build more resilient fabrics that accommodate growth, support virtualization and containerized workloads, and deliver a more predictable, service-level friendly network. If you are upgrading existing interconnects or starting a new deployment, the HPE M-Series 100GbE QSFP28 PSM4 500m transceiver is designed to be a drop-in, field-proven solution that minimizes disruption while maximizing throughput and reliability. The combination of a robust 1310 nm channel, high-bandwidth lanes, and a proven form factor translates into a transceiver that engineers and IT managers can rely on for today’s data-intensive tasks and tomorrow’s expansion plans. It also aligns with environmental and energy-efficient design goals because it consolidates high capacity into a compact package, reducing cable clutter and helping to optimize cooling and airflow around dense switching environments. In short, this transceiver is about giving data centers, HPC clusters, and enterprise networks a foundation they can trust as they scale, migrate, and modernize without compromising on performance or service quality.

• High-performance 100 GbE connection in a QSFP28 form factor using 4x25 Gbps PSM4 lanes, enabling parallel data transfer that reduces serialization delay and helps sustain throughput under heavy workloads. This design supports dense interconnects in data centers, HPC racks, and cloud deployments where every nanosecond counts. It also facilitates scalable uplinks from racks to aggregation layers, helping to simplify cabling strategies and minimize switch port contention.
• 1310 nm short-reach transceiver optimized for low-latency interconnects across data centers. The 1310 nm window provides favorable attenuation characteristics on single-mode fiber, helping to maintain strong signal integrity across the 500-meter reach and enabling reliable operation in challenging cabling paths. This wavelength choice supports stable performance in environments with tight fiber routing and temperature variation, contributing to predictable latency and BER.
• 500 meter reach over single-mode fiber OS2 with MPO/MTP-12 interface, empowering scalable topologies from top-of-rack to aggregation layers while simplifying fiber management in dense deployments. The long reach reduces the need for additional intermediate devices, lowers total cost of ownership, and enables flexible network designs that can adapt to future growth without rearchitecting the fabric.
• Designed for HPE StoreFabric M-Series Interconnects to ensure consistent performance, compatibility, and reliability across the fabric. By aligning with StoreFabric’s performance goals, these transceivers help you achieve predictable latency, bandwidth, and error performance in multi-vendor environments while preserving interoperability with HPE partner ecosystems. This synergy supports streamlined management, easier troubleshooting, and a cohesive monitoring experience across the fabric.
• Hot-pluggable, easily replaceable QSFP28 module that supports standard enterprise procedures for installation and maintenance. It snaps into a supported switch or server port with minimal downtime, enabling fast upgrades, field replacements, and non-disruptive maintenance in busy data centers. The rugged design is tuned for reliability in dense racks, and the module integrates smoothly with common management tools to simplify status checks and performance validation.

how to install HPE M-Series 100GbE QSFP28 1310nm PSM4 500m Transceiver

• Verify that your switch or server port is QSFP28-capable and supports 100GBASE-PSM4 operation. Review vendor guidelines for compatibility and firmware requirements before installation.
• Power down the device or follow hot-swap procedures as dictated by your equipment policy. Handle the transceiver with proper ESD protection and avoid touching optical surfaces.
• Align the QSFP28 module with the corresponding port and gently insert until the lateral latch engages. Do not force the module; if it does not seat easily, re-orient and try again.
• Connect the fiber using an MPO/MTP-12 trunk to the MPO/MTP-12 footprint on the transceiver and the corresponding port on the other end. Use single-mode OS2 fiber and maintain recommended bend radii to protect signal integrity.
• Ensure fiber cleanliness and connector integrity prior to insertion. After installation, power up the device and verify link status through the management interface or CLI. Confirm that the port negotiates to 100G with the correct lane configuration and monitor for any errors or alarms.
• Run basic throughput and latency tests to validate the interconnect meets your performance targets. If issues arise, check for compatibility, firmware versions, and cabling quality before contacting support.

Frequently asked questions

• What is the HPE M-Series 100GbE QSFP28 1310nm PSM4 500m Transceiver? It is a high-performance, 100 Gigabit Ethernet transceiver in the QSFP28 form factor that uses four parallel 25 Gbps lanes (PSM4) with a 1310 nm wavelength, designed for 500-meter reach on single-mode OS2 fiber and MPO/MTP-12 connections. Built for HPE StoreFabric environments, it delivers reliable, scalable interconnects between compute nodes and switch fabrics.
• What is PSM4, and how does it differ from other 100G transceivers? PSM4 stands for Parallel Single-Mode 4-lane. Unlike shared-lane 100G approaches, PSM4 uses four discrete 25 Gbps channels in parallel, enabling high-throughput, low-latency connections over single-mode fiber with multi-fiber connectors. This configuration is well-suited for short-to-mid-range data-center interconnects and reduces optical complexity in certain deployments.
• What is the maximum reach of this transceiver? The transceiver is specified for a reach of up to 500 meters on single-mode OS2 fiber, making it appropriate for top-of-rack to aggregation links and campus-scale interconnects where longer fiber runs are required.
• What fiber and connector does it use? It uses single-mode fiber (OS2) with an MPO/MTP-12 connector, common for parallel optical interconnects in 100G QSFP28 deployments.
• Is it compatible with all 100G switches and servers? The transceiver is designed for compatibility with switches and servers that support QSFP28 100GBASE-PSM4 interfaces and store fabric ecosystems. Always verify vendor-specific compatibility and firmware requirements before purchase or installation to ensure optimal interoperability.
• How do I install and verify a link after installation? Install the transceiver following the standard hot-swap or powered insertion procedure, connect the MPO/MTP-12 fiber, and power up the device. Use the management interface to verify port status, link speed (100G), and lane configuration, then run basic throughput tests to confirm performance targets are met. Monitor for errors and adjust cabling or firmware if needed.
